Settling time is the time it takes the output of the amplifier to  
reach and remain within a percentage of its final value after a  
pulse is applied at the input. The AD8510/AD8512/AD8513  
settle to within 0.01% in less than 900 ns with a step of 0 V to  
10 V in unity gain. This makes each of these parts an excellent  
choice as a buffer at the output of DACs whose settling time is  
typically less than 1 μs.

In addition to the fast settling time and fast slew rate, low offset  
voltage drift and input offset current maintain the full accuracy  
of 12-bit converters over the entire operating temperature range.  
TIME (2µs/DIV)  
OVERLOAD RECOVERY TIME  
Figure 44. Negative Overload Recovery  
Overload recovery, also known as overdrive recovery, is the  
time it takes the output of an amplifier to recover to its linear  
region from a saturated condition. This recovery time is par-  
ticularly important in applications where the amplifier must  
amplify small signals in the presence of large transient voltages.  
CAPACITIVE LOAD DRIVE  
The AD8510/AD8512/AD8513 are unconditionally stable at all  
gains in inverting and noninverting configurations. Each device  
is capable of driving a capacitive load of up to 1000 pF without  
oscillation in unity gain using the worst-case configuration.  
Figure 43 shows the positive overload recovery of the AD8510/  
AD8512/AD8513. The output recovers in approximately 200 ns  
from a saturated condition.  
However, as with most amplifiers, driving larger capacitive  
loads in a unity gain configuration may cause excessive  
overshoot and ringing, or even oscillation. A simple snubber  
network significantly reduces the amount of overshoot and  
ringing. The advantage of this configuration is that the output  
swing of the amplifier is not reduced, because RS is outside the  
feedback loop.

Figure 45. Snubber Network Configuration  
The negative overdrive recovery time shown in Figure 44 is less  
than 200 ns.  
In addition to the fast recovery time, the AD8510/AD8512/  
AD8513 show excellent symmetry of the positive and negative  
recovery times. This is an important feature for transient signal  
rectification because the output signal is kept equally undistorted  
throughout any given period.
